Q. 6.Why is Eucalyptus targeted for genetic modification studies?

Ans. Eucalyptus is used as a raw material in pulp and rayon industries and is planted even in wastelands. Estimated area under Eucalyptus in India is 25,00,000 ha. Moreover, Eucalyptus is an introduced species and there are no natural populations of Eucalyptus in India, thereby reducing concerns on transgene escape into the wild. Eucalyptus is amenable for in vitro regeneration as well as macro propagation, thus enabling easy propagation of genetically modified trees. The Institute also has an ongoing program for Eucalyptus improvement. Superior genotypes have been selected for seed orchards and plantation programmes.

 

Q. 7. What are the traits being targeted for genetic modification?

Ans. In the study on Eucalyptus and Casuarina, the IFGTB, Coimbatore have found that dominant markers like ISSR and RAPD can be used at species level differentiation while ISSR, FISSR, AFLP and SSR were found suitable for sub specific taxa including provenances and clones.

Q. 9.What are the softwares used in genetic diversity estimation using molecular data?

Ans. The softwares used for genetic diversity estimation using DNA marker data (dominant and co dominant include NTSys, POPGENE, WINBOOT, Arlequin and DNAPOP.

 

Q. 10.How to develop SSRs in species with no sequence information? Is there any alternate strategy available for SSR enrichment?

Ans. Development of a microsatellite marker system for a new species requires isolation, cloning, sequencing and characterization of microsatellite loci. Several procedures are available for the enrichment of microsatellites in genomic library like use of anchored repeat primers or probes to improve the efficiency of microsatellite isolation The development of microsatellite markers through these laboratory based screening of SSR libraries is highly time consuming and expensive. An alternate strategy is to cross amplify SSRs across species or genera followed by construction of enriched library and subsequent sequencing and development of primers. This strategy was used to develop SSRs in Casuarina equisetifolia.

 

Q. 11.Are there any specific DNA markers to identify different Eucalyptus species?

Ans. The species-specific ISSR markers for E. camaldulensis, E. grandis, E. urophylla and E. citriodora have been developed, while no specific markers could be detected in E. tereticornis. However, work is in progress in ICFRE to identify SSR markers specific to E. tereticornis.

 

Q. 12. What are the advantages of association mapping over QTL mapping?

Ans. Association mapping is a recent concept used in phenotype &ndash marker association based on linkage disequilibrium (LD existing in a natural population while QTL mapping involves linkage of marker with trait in a segregating population. In tree species with long gestation period, generation of segregating populations with contrasting phenotypes is time-consuming, hence, association mapping on candidate genes can be an alternate approach where an unstructured population can be used. Here the marker is present very close to the candidate gene (in kilobasepairs or within the candidate gene as SNPs reducing the number of segregating generations for validation.

Q. 50.Why wood develops cracks during drying?

Ans.It is due to excessive moisture loss in a short duration.

 

Q. 51. How to protect wood logs/planks from end cracking?

Ans. The cracks at the ends can be avoided by coating with the ends with bitumen paint or other sealants.

 

Q. 52. Once wood is seasoned will it be always dry?

Ans. Wood is a hygroscopic material. During various operations like sawing, boring, mortising, planning, etc. done on wood for making a product, the cells of wood present on the surface cut open. If these cut cells are not sealed properly by using, primer and paint coats, wax coats, etc., wood absorbs water from surrounding atmosphere, particularly during rainy season and gets wet. Hence, it is necessary to seal a product with coatings so that it becomes dimensionally stable. Sealing is also necessary for avoiding surface cracks in products during its service life.
